Rx FIFO Register.
For characters shorter than 8 bits the unused bits are set to zero
Bit 7
BIT 6
Bits of the received data characters.

CR A and B Command Register
CR, one for each channel, controls the channel commands and
enables/disables the receiver and transmitter. Commands may be to
the upper and lower four bits in the same bus cycle. If both enable
and disable bits are set to 1 in the lower four bits a disable will
result.
